What does Signed media URL mean?
A signed media URL is an address carrying information that a server uses to validate access, often including a signature and an expiry condition. Its exact design is service-specific, and the complete address can be sensitive even when the path looks ordinary.

Signed links can be temporary entry points rather than permanent source addresses. Removing or editing their parameters can invalidate access. Do not upload them to public playback testers or include them unredacted in support screenshots. Use the documented account or playlist route so the player can obtain current access when appropriate.
